The thermometer
The thermometer was invented by Galileo in th year 1593. The thermometer was made of water and a glass bulb. The water would move up and down the bulb as the temperature changed.

Newton presented the 3 laws of motion around the age 66 in the year of 1686. In his first law he talk about Inertia, in the second law he talked about F=ma, and in his third law he stated that for every action there is a equal and opposite reaction. If it weren't for the laws we wouldn't understand motion. -
